Sony WF-L910 WZ Wireless Earphones LinkBuds Open Splash-proof and waterproof Bluetooth compatible

Open listening style that doesn't block your ears
The newly developed ring-shaped driver unit with an open center of the diaphragm further improves sound pressure from the previous model (LinkBuds). Since the ear canal is not blocked, there is no feeling of pressure, and you can enjoy a new listening style in which you can clearly hear the surrounding sounds even when wearing earphones.
